Description

[Detailed description of the invention] The present invention has a square shape that can be used as a container body when transporting foods such as frozen desserts and fresh cakes made with fresh cream in a cold state, and can also be used as a lid for the container body. It relates to transportation containers.

As described in Japanese Utility Model Publication No. 54-9554, a rectangular transportation container is known that can be used as a container body and can also be used as a lid for the container body.

However, in such a square transportation container, if the square transportation container used as the lid body is placed over the square transportation container used as the container body to form a square transportation container with a lid, There was a drawback in that the rectangular transport container used as the container body easily came off from the rectangular transport container used as the container body.

The present invention was devised to eliminate such drawbacks, and as explained below with reference to the drawings, the present invention is a rectangular transportation container that can be used both as a container body and as a lid for the container body. , the bottom plate and the four side walls are formed thickly, and four recesses 2 are formed on the outer surfaces of the two parallel side walls at positions equidistant from the vertical center line, leaving the edge 1 around the opening, so that they are mutually Attached to the two recesses 2 whose positions are diagonal to each other are the fasteners 3, which are rotatable around the fixed end and which has a roller pivotally supported at its tip, and the remaining two recesses 2 are fitted with the ends of the edges 1. This invention relates to a rectangular transportation container characterized by having a protrusion 4 on the lower surface side.

The rectangular transportation container is made thick by having a bottom plate and four side walls with a core material such as foamed polyurethane or foamed polystyrene, and an insulating structure in which both the inside and outside surfaces are covered with polyethylene, polypropylene, etc.

Four recesses 2 are formed on the outer surfaces of the two parallel side walls at positions equidistant from the vertical center line, leaving an edge 1 around the opening.

A fastener 3 with a roller supported rotatably at the distal end rotatable around a fixed end is attached to two recesses 2 diagonally diagonal to each other, and an edge 1 is attached to the remaining two recesses 2. A protrusion 4 is provided on the lower surface side.

Place the second container on top of the rectangular transport container with the opening facing upward.
As shown in the figure, another rectangular transport container is repeatedly folded and stacked on top of each other to form a lid body, and as shown in Figures 3 and 4, the fastener 3
By making the rollers cross over the protrusion 4 provided on the edge 1 of the other square transportation container and hook them, the square transportation containers can be securely fixed to each other. To prevent a mold transport container from being accidentally detached from a square transport container used as a container body.

When removing the square transport container used as a lid,
After pushing the roller of the fastener 3 outward over the protrusion 4 provided on the edge 1 of the other party's square transportation container,
All you have to do is remove the rectangular transport container used as the lid.

A protrusion 5 that protrudes above the opening along the inner surface of the side wall of the square transportation container, and a recessed portion 6 that is sunken below the opening along the inner surface of the side wall are arranged opposite to each parallel side wall. The length and width of the protruding portion 5 are approximately equal to the length and width of the depressed portion 6, and the height of the protruding portion 5 is made equal to the length and width of the depressed portion 6.
When the depth is approximately equal to the depth of the rectangular transport container installed with the opening facing upward, another rectangular transport container is repeatedly stacked on top of the rectangular transport container to form a lid, as shown in Figure 2. , the protrusion 5 of the upper square transport container fits into the recess 6 of the lower square transport container, and the protrusion 5 of the lower square transport container fits into the recess 6 of the upper square transport container. As a result, the upper square transportation container can be prevented from shifting forward, backward, left, and right.

In addition, as shown in Fig. 2, a plurality of protrusions 7 are formed diagonally and parallel to each other in the areas where the outer surface of the lower plate of the square transportation container is divided into four areas: upper right, lower right, upper left, and lower left. However, although the directions of the protrusions 7 are different between areas adjacent to each other in the vertical and horizontal directions, they are the same in areas adjacent to each other in the opposing line direction, and from the protrusions 7 formed between each area to the outer surface of the bottom plate. If we assume an extension line extending to the center line 8 that divides the area into left and right halves, the angle formed by the center line 8 and each extension line is the same, and the extension lines alternate from the adjacent areas on the left and right. When the protrusion 7 is formed so as to reach the center line 8, the rectangular transport containers are stacked together as described above to form a rectangular transport container with a lid as shown in FIG. When further stacked, the protrusion 7 formed diagonally on the outer surface of the bottom plate of the rectangular transportation container with a lid located in the upper row was formed diagonally on the outer surface of the lid of the rectangular transportation container with lid located in the lower row. Since it fits between the protrusions 7, it is possible to prevent the stacked square transportation containers with lids from shifting back and forth and left and right.

The square transportation container according to the present invention is produced by repeatedly stacking the square transportation container used as the lid on top of the square transportation container used as the container body, and then the rollers of the fasteners 3 are placed on top of the square transportation container used as the container body. By climbing over the protrusion 4 provided on the edge 1 of the transportation container and hooking it, the square transportation containers can be firmly fixed to each other, and the square transportation container used as the lid can be used as the container body. Since the container does not accidentally come off the square transportation container, it is possible to suitably configure a square transportation container with a lid that is used when transporting food.
